title: Usefulness of the Global Echo-Doppler Score (GEDS) in selection of patients with mitral stenosis for percutaneous balloon mitral valvuloplasty.
abstract: BACKGROUND
  We aimed to create a novel modified score by combining anatomic and hemodynamic Doppler-echocardiographic measures for selection of suitable patients with mitral stenosis for percutaneous balloon mitral valvuloplasty (PBMV) and its impact in prediction of outcome.
  
  
  METHODS
  262 consecutive patients candidate for PBMV were enrolled. Wilkins score and a global score based on anatomical parameters (Wilkins score, posterior to anterior mitral leaflet ratio [PMVL/AMVL ratio]; left atrial diameter [LAD]) and hemodynamic parameters (mitral regurgitation [MR]; atrioventricular compliance [CN]; systolic pulmonary artery pressure [SPAP]) were assessed. Patients were classified into two groups according to their outcomes.
  
  
  RESULTS
  Global Echo-Doppler Score (GEDS) for patients with favorable vs. those with unfavorable outcomes was (5.0 ± 0.9 vs. 8.9 ± 1.3; p < 0.001). Sensitivity, specificity, and accuracy of a GEDS ≥ 7 for prediction of cardiac events were 97.5%, 88%, and 97.5%, respectively. The area under the receiver operating characteristic curve was 0.95 (p < 0.001). The correlation coefficient was 0.852 (p < 0.0001) for GEDS 0.531 (p < 0.002), for Wilkins score 0.315 (p < 0.02), for PMVL/AMVL 0.460 (p < 0.01), for LAD; MR: Pre-PBMV (r = 0.348, p < 0.03); CN [mL/mm Hg] (r = 0.579, p < 0.01) and SPAP [mm Hg] (r = 0.499, p < 0.01). In the regression analysis, GEDS, Wilkins score, and LAD were entered into the model. The regression coefficient (r = 0.695) of GEDS was much higher than those of the other 2 factors.
  
  
  CONCLUSIONS
  GEDS is an independent predictor of PBMV success and clinical outcome and may be formulated in a scoring system that would help to identify the proper timing and best candidates for PBMV.
